The goal of liberalism is the peaceful cooperation of all men. It aims at peace among nations too. When there is private ownership of the means of production everywhere and when laws, the tribunals and the administration treat foreigners and citizens on equal terms, it is of little importance where a country's frontiers are drawn. ... War no longer pays; there is no motive for aggression. ... All nations can coexist peacefully...

The characteristic feature of militarism is not the fact that a nation has a powerful army or navy. It is the paramount role assigned to the army within the political structure. Even in peacetime the army is supreme; it is the predominant factor in political life. The subjects must obey the government as soldiers must obey their superiors. Within a militarist community there is no freedom; there are only obedience and discipline.

Inflation is an increase in the quantity of money without a corresponding increase in the demand for money, i.e., for cash holdings.

The Free Market and Its Enemies, speech to the Foundation for Economic Education[1] (1951)

If one rejects laissez faire on account of man's fallibility and moral weakness, one must for the same reason also reject every kind of government action.

Planning for Freedom (1952), p. 44

You have the courage to tell the masses what no politician told them: you are inferior and all the improvements in your conditions which you simply take for granted you owe to the effort of men who are better than you. If this be arrogance, as some of your critics observed, it is still the truth that had to said in the age of the Welfare State.

Mises' letter to Ayn Rand praising Atlas Shrugged,(23 January 1958), quoted in Mises: The Last Knight of Liberalism (2007).

Socialism is the watchword and the catchword of our day. The socialist idea dominates the modem spirit. The masses approve of it. It expresses the thoughts and feelings of all; it has set its seal upon our time. When history comes to tell our story it will write above the chapter "The Epoch of Socialism."
As yet, it is true, Socialism has not created a society which can be said to represent its ideal. But for more than a generation the policies of civilized nations have been directed towards nothing less than a gradual realization of Socialism.

Introduction : The Success of Socialist Ideas

All rational action is economic. All economic activity is rational action. All rational action is in the first place individual action. Only the individual thinks. Only the individual reasons. Only the individual acts.

Permanent mass unemployment destroys the moral foundations of the social order. The young people, who, having finished their training for work, are forced to remain idle, are the ferment out of which the most radical political movements are formed. In their ranks the soldiers of the coming revolutions are recruited.

Repression by brute force is always a confession of the inability to make use of the better weapons of the intellect — better because they alone give promise of final success. This is the fundamental error from which Fascism suffers and which will ultimately cause its downfall..

Now it cannot be denied that the only way one can offer effective resistance to violent assaults is by violence. Against the weapons of the Bolsheviks, weapons must be used in reprisal, and it would be a mistake to display weakness before murderers. No liberal has ever called this into question. What distinguishes liberal from Fascist political tactics is not a difference of opinion in regard to the necessity of using armed force to resist armed attackers, but a difference in the fundamental estimation of the role of violence in a struggle for power. The great danger threatening domestic policy from the side of Fascism lies in its complete faith in the decisive power of violence. In order to assure success, one must be imbued with the will to victory and always proceed violently. This is its highest principle. What happens, however, when one's opponent, similarly animated by the will to be victorious, acts just as violently? The result must be a battle, a civil war. The ultimate victor to emerge from such conflicts will be the faction strongest in number. In the long run, a minority — even if it is composed of the most capable and energetic — cannot succeed in resisting the majority. The decisive question, therefore, always remains: How does one obtain a majority for one's own party? This, however, is a purely intellectual matter. It is a victory that can be won only with the weapons of the intellect, never by force. The suppression of all opposition by sheer violence is a most unsuitable way to win adherents to one's cause. Resort to naked force — that is, without justification in terms of intellectual arguments accepted by public opinion — merely gains new friends for those whom one is thereby trying to combat. In a battle between force and an idea, the latter always prevails.

Repression by brute force is always a confession of the inability to make use of the better weapons of the intellect — better because they alone give promise of final success. This is the fundamental error from which Fascism suffers and which will ultimately cause its downfall. The victory of Fascism in a number of countries is only an episode in the long series of struggles over the problem of property. The next episode will be the victory of Communism. The ultimate outcome of the struggle, however, will not be decided by arms, but by ideas. It is ideas that group men into fighting factions, that press the weapons into their hands, and that determine against whom and for whom the weapons shall be used. It is they alone, and not arms, that, in the last analysis, turn the scales.
So much for the domestic policy of Fascism. That its foreign policy, based as it is on the avowed principle of force in international relations, cannot fail to give rise to an endless series of wars that must destroy all of modern civilization requires no further discussion. To maintain and further raise our present level of economic development, peace among nations must be assured. But they cannot live together in peace if the basic tenet of the ideology by which they are governed is the belief that one's own nation can secure its place in the community of nations by force alone.It cannot be denied that Fascism and similar movements aiming at the establishment of dictatorships are full of the best intentions and that their intervention has, for the moment, saved European civilization. The merit that Fascism has thereby won for itself will live on eternally in history. But though its policy has brought salvation for the moment, it is not of the kind which could promise continued success. Fascism was an emergency makeshift. To view it as something more would be a fatal error.

A free man must be able to endure it when his fellow men act and live otherwise than he considers proper. He must free himself from the habit, just as soon as something does not please him, of calling for the police.

As the liberal sees it, the task of the state consists solely and exclusively in guaranteeing the protection of life, health, liberty, and private property against violent attacks. Everything that goes beyond this is an evil. A government that, instead of fulfilling its task, sought to go so far as actually to infringe on personal security of life and health, freedom, and property would, of course, be altogether bad.

The characteristic mark of this age of dictators, wars and revolutions is its anti-capitalistic bias. Most governments and political parties are eager to restrict the sphere of private initiative and free enterprise. It is an almost unchallenged dogma that capitalism is done for and that the coming of all-round regimentation of economic activities is both inescapable and highly desirable.

Government spending cannot create additional jobs. If the government provides the funds required by taxing the citizens or by borrowing from the public, it abolishes on the one hand as many jobs as it creates on the other. If government spending is financed by borrowing from the commercial banks, it means credit expansion and inflation. If in the course of such an inflation the rise in commodity prices exceeds the rise in nominal wage rates, unemployment will drop. But what makes unemployment shrink is precisely the fact that real wage rates are falling.

Credit expansion can bring about a temporary boom. But such a fictitious prosperity must end in a general depression of trade, a slump.

The interventionists do not approach the study of economic matters with scientific disinterestedness. Most of them are driven by an envious resentment against those whose incomes are larger than their own. This bias makes it impossible for them to see things as they really are. For them the main thing is not to improve the conditions of the masses, but to harm the entrepreneurs and capitalists even if this policy victimizes the immense majority of the people.

No social co-operation under the division of labour is possible when some people or unions of people are granted the right to prevent by violence and the threat of violence other people from working. When enforced by violence, a strike in vital branches of production or a general strike are tantamount to a revolutionary destruction of society.

Whatever people do in the market economy, is the execution of their own plans. In this sense every human action means planning. What those calling themselves planners advocate is not the substitution of planned action for letting things go. It is the substitution of the planner's own plan for the plans of his fellow-men. The planner is a potential dictator who wants to deprive all other people of the power to plan and act according to their own plans. He aims at one thing only: the exclusive absolute pre-eminence of his own plan.

When people were committed to the idea that in the field of religion only one plan must be adopted, bloody wars resulted. With the acknowledgment of the principle of religious freedom these wars ceased. The market economy safeguards peaceful economic co-operation because it does not use force upon the economic plans of the citizens. If one master plan is to be substituted for the plans of each citizen, endless fighting must emerge. Those who disagree with the dictator's plan have no other means to carry on than to defeat the despot by force of arms.

State and government are the social apparatus of violent coercion and repression. Such an apparatus, the police power, is indispensable in order to prevent anti-social individuals and bands from destroying social co-operation. Violent prevention and suppression of anti-social activities benefit the whole of society and each of its members. But violence and oppression are none the less evils and corrupt those in charge of their application. It is necessary to restrict the power of those in office lest they become absolute despots. Society cannot exist without an apparatus of violent coercion. But neither can it exist if the office holders are irresponsible tyrants free to inflict harm upon those they dislike.

All this talk: the state should do this or that, ultimately means: the police should force consumers to behave otherwise than they would behave spontaneously.

In fact, however, the supporters of the welfare state are utterly anti-social and intolerant zealots. For their ideology tacitly implies that the government will exactly execute what they themselves deem right and beneficial. They entirely disregard the possibility that there could arise disagreement with regard to the question of what is right and expedient and what is not. They advocate enlightened despotism, but they are convinced that the enlightened despot will in every detail comply with their own opinion concerning the measures to be adopted. They favour planning, but what they have in mind is exclusively their own plan, not those of other people. They want to exterminate all opponents, that is, all those who disagree with them. They are utterly intolerant and are not prepared to allow any discussion. Every advocate of the welfare state and of planning is a potential dictator. What he plans is to deprive all other men of all their rights, and to establish his own and his friends' unrestricted omnipotence. He refuses to convince his fellow-citizens. He prefers to "liquidate" them. He scorns the "bourgeois" society that worships law and legal procedure. He himself worships violence and bloodshed.

From a correct Marxian point of view … all measures designed to restrain, to regulate and to improve capitalism were simply "petty-bourgeois" nonsense … True socialists should not place any obstacles in the way of capitalist evolution. For only the full maturity of capitalism could bring about socialism. It is not only vain, but harmful to the interests of the proletarians to resort to such measures.

For the time being, the ominous peril of the communist parties in the West lies in their stand on foreign affairs. The distinctive mark of all present-day communist parties is their devotion to the aggressive foreign policy of the Soviets. Whenever they must choose between Russia and their own country, they do not hesitate to prefer Russia. Their principle is: Right or wrong, my Russia. They strictly obey all orders issued from Moscow. When Russia was an ally of Hitler, the French communists sabotaged their own country's war effort and the American communists passionately opposed President Roosevelt's plans to aid England and France in their struggle against the Nazis.

It is, they say, not Russia that plans aggression but, on the contrary, the decaying capitalist democracies. Russia wants merely to defend its own independence. This is an old and well-tried method of justifying aggression. Louis XIV and Napoleon I, Wilhelm II and Hitler were the most peace-loving of all men. When they invaded foreign countries, they did so only in just self-defence. Russia was as much menaced by Estonia or Latvia as Germany was by Luxemburg or Denmark.

It is a fact that Mussolini entered the scene of world politics as an ally of the democracies, while Lenin entered it as a virtual ally of imperial Germany.

There were nowhere more docile disciples of Lenin, Trotsky and Stalin than the Nazis were.

The only certain fact about Russian affairs under the Soviet regime with regard to which all people agree is: that the standard of living of the Russian masses is much lower than ... the paragon of capitalism, the United States of America. If we were to regard the Soviet regime as an experiment, we would have to say that the experiment has clearly demonstrated the superiority of capitalism and the inferiority of socialism.

The capitalist system of production is an economic democracy in which every penny gives a right to vote. The consumers are the sovereign people. The capitalists, the entrepreneurs, and the farmers are the people’s mandatories. If they do not obey, if they fail to produce, at the lowest possible cost, what the consumers are asking for, they lose their office. Their task is service to the consumer. Profit and loss are the instruments by means of which the consumers keep a tight rein on all business activities.

A man who chooses between drinking a glass of milk and a glass of a solution of potassium cyanide does not choose between two beverages; he chooses between life and death. A society that chooses between capitalism and socialism does not choose between two social systems; it chooses between social cooperation and the disintegration of society. Socialism is not an alternative to capitalism; it is an alternative to any system under which men can live as human beings.

Human Action : A Treatise on Economics (1966)

There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved.

If one takes pleasure in calling the gold standard a "barbarous relic," one cannot object to the application of the same term to every historically determined institution. Then the fact that the British speak English — and not Danish, German, or French — is a barbarous relic too, and every Briton who opposes the substitution of Esperanto for English is no less dogmatic and orthodox than those who do not wax rapturous about the plans for a managed currency.

Value is not intrinsic, it is not in things. It is within us; it is the way in which man reacts to the conditions of his environment. Neither is value in words and doctrines, it is reflected in human conduct. It is not what a man or groups of men say about value that counts, but how they act.

People do not cooperate under the division of labor because they love or should love one another. They cooperate because this best serves their own interests. Neither love nor charity nor any other sympathetic sentiments but rightly understood selfishness is what originally impelled man to adjust himself to the requirements of society, to respect the rights and freedoms of his fellow men and to substitute peaceful collaboration for enmity and conflict.

The criterion of truth is that it works even if nobody is prepared to acknowledge it.

Chapter 5: On Some Popular Errors Concerning the Scope and Method of Economics, § 9 : The Belief in the Omnipotence of Thought

It is a double-edged makeshift to entrust an individual or a group of individuals with the authority to resort to violence. The enticement implied is too tempting for a human being. The men who are to protect the community against violent aggression easily turn into the most dangerous aggressors. They transgress their mandate. They misuse their power for the oppression of those whom they were expected to defend against oppression. The main political problem is how to prevent the police power from becoming tyrannical. This is the meaning of all the struggles for liberty.

Chapter 5: On Some Popular Errors Concerning the Scope and Method of Economics, § 10 : The Concept of a Perfect System of Government

Professor von Mises has a splendid analytical mind and an admirable passion for liberty; but as a student of human nature he is worse than null and as a debater he is of Hyde Park standard.

The Economist magazine, "Liberalism in Caricature", (Review of The Anti-Capitalist Mentality) April 13, 1957.

Rothbard was right that Mises’s and Hayek’s economic thought should be dehomogenized. Hayek described Mises’s Theory of Money and Credit as “for many years the most profound and satisfying work on the subject available.” Certainly it was an extraordinarily prescient work, with Mises speculating in 1912 that the value of money could drop to one-hundredth of its former value within a twelve-month period. What was once thought impossible became reality within a decade. [...] Hayek’s trade cycle theory was not in essence the same as Mises’s.

While it is possible to imagine Mises without Hayek, it is not possible to imagine Hayek without Mises. Hayek’s great accomplishment was to enunciate the idea of the “division of knowledge” and to explore its ramifications in various areas. Many economists have been and continue to be influenced by Ludwig von Mises. A great teacher lives on in the life and work of his students and their students. Mises’s contribution was lasting, which can be said of so few.

Though I learned that he [Mises] usually was right in his conclusions, I wasn't always satisfied by his arguments, and retained to the end a certain critical attitude which sometimes forced me to build different constructions, which however, to my great pleasure, usually led to the same conclusions. I am to the present moment pursuing the questions which he made me see, and that, I believe is the greatest benefit one scientist can confer on one of the next generation.

...there I came to know him (Mises) mainly as a tremendously efficient executive, the kind of man who, as was said of John Stuart Mill, because he does a normal day's work in two hours, always has a clear desk and time to talk about anything. I came to know him as one of the best educated and informed men I have ever known...

The dictatorship of the proletariat was the logical extension of Lenin’s agitprop; Fascism was more than the logical extension of liberty – it was embraced by Ludwig von Mises (1985 [1927], 42–51), the co-leader of the third generation Austrian School, [...]
Mises’ political activity was consistent with his ideology: on 1 March 1934, he joined the Austro-Fascist Patriotic Front and their Werk Neues Leben social club (Hülsmann 2007, 677, n149). Mises may also have been a victim of propaganda: his justification for this tactical embrace was that fascists would protect property – the protection of which he saw as the very essence of liberty. [...] The Jewish-born Mises was lucky to escape with his life; he devoted much of the rest of it to describing his opponents as ‘Fascists’.
